THERMAL CONDUCTIVITY OF ALUMINUM-LITHIUM ALLOYS CONTAINING UP TO 8% LITHIUM

Description: The thermal conductivities of Al-Li alloys containing up to 8 wt.% lithium were determined at 125 to 260 deg C. The addition of lithium to aluminum sharply reduces the conductivity from 0.60 cal/(sec) deg C)(cm) for pure aluminum to 0.22 cal/(sec)( deg C)(cm) for 2 wt.% alloys; further addition linearly and more gradually decreases the conductivity to 0.16 cal/(sec)( deg C)(cm) for a 7.9 wt.% alloy.

The Diffusion of Lithium in Aluminum

Description: The diffusion of lithium in aluminum was measured at various temperatures with diffusion couples of aluminum-LiAl. The activation energy, E, is 33.3 kcal/mol, and the diffusion factor, Do, is 4.5 cm{sup2}/sec. (auth)
